I like it.

BTW, there is another problem in `set-variable'.  When setting
a customizable variable with `set-variable' it doesn't use its
`:set' keyword to set the value.  For example,

    M-x set-variable RET frame-background-mode RET dark RET

doesn't update the background mode until `frame-set-background-mode'
is run explicitly.

`set-variable' already uses internal functions of the `custom' package
to test the custom type, so why wouldn't it also run a setter specified
by the `:set' custom keyword?
